1. Univ logo Fuel composition and engine control using state-space and neural network By KinYip Chan Supervised by Prof. Andrzej Ordys, Dr. Olga Duran, Dr. Olga Duran, Dr. Konstantin Volkov Dr. Konstantin Volkov Dr. Jiamei Deng Dr. Jiamei Deng UKACC PhD Presentation Showcase

2. Univ logo UKACC PhD Presentation Showcase Slide 2 Introduction  Fuel composition is supply by suppliers  Named Gasoline(Petrol) or Diesel  Contains hydrocarbon atoms  Mix with Methanol, Ethanol (Alcohol)  Composition varies  Fuel identification  Further Engine Control

3. Univ logo UKACC PhD Presentation Showcase Slide 3 Motivation and methodology  Background and motivation for research  Lower emissions  Better fuel economy  Improve engine performance  Research methodology  Emission – non-linear behaviour (CO2, CO, O2, NOx)  Computer based engine simulation  Fuel estimation C H O  System identification – state-space, LQR, neural network  Tune controller  Current status  System identified  Different speed and torque Real engine simulationReal engine simulation
